Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561784, here are decompositions:

  • 17 + 561767 = 561784
  • 23 + 561761 = 561784
  • 71 + 561713 = 561784
  • 233 + 561551 = 561784
  • 263 + 561521 = 561784
  • 593 + 561191 = 561784
  • 683 + 561101 = 561784
  • 701 + 561083 = 561784

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 561,784 and was likely granted around 1895.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 561784 first appears in π at position 293,100 of the decimal expansion (the 293,100ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
